Mississippi's Data Center Incentive Framework

New data centers in Mississippi benefit from one of the most comprehensive state-level incentive frameworks in the United States. The MDA's Data Center Enterprises tax exemption waives state sales and use taxes on all computing hardware, equipment, and software for facilities certified as data centers by the agency. 

The Mississippi Major Economic Impact Act provides an additional layer of stacked benefits: companies investing at least USD 300 million and creating 30 jobs qualify for up to 10 years of state income-tax rebates, sales- and use-tax exemptions on construction materials, and property-tax exemptions frequently extended through PILOT agreements lasting 20 to 30 years.

The state's Advantage Jobs Incentive Programme also refunds up to 90 percent of payroll taxes depending on job count, wages, and county location. For data centers specifically, companies creating at least 100 jobs at the average state or county wage qualify for a 70 percent payroll cash rebate, including bonuses and overtime. If salaries exceed 175 percent of the state average wage, the rebate rises to 90 percent. In more developed counties, the threshold rises to 200 jobs.

As of early 2026, Mississippi has secured five major data center projects totalling roughly USD 49 billion in headline investment. Critics, including the Center for Economic Accountability, have noted that Mississippi's framework allows companies to operate near zero effective tax liability for decades, and that job-creation benchmarks are set low enough that facilities can substantially underperform early claims and still qualify.
